Company profile
researched Aug 2026Exosphere (엑소스피어, marketed in Japan as EXOセキュリティ) is a cloud-delivered endpoint security service that bundles malware defense and data loss prevention (DLP) into a single product. Advertised capabilities include PC anti-virus, ransomware protection, file exfiltration prevention, removable media (USB) control, group policy management, web access control, IT asset information collection, screen capture blocking, print/output security, personal information detection and encryption, file attachment control, application execution control, harmful site blocking, security alerts and centralized administration.
The product is positioned for non-specialist administrators at small and mid-sized organizations, with a self-service onboarding flow in which signing up and installing the agent produces a diagnosis of the organization's PC security posture, plus daily security reports. macOS endpoints are supported for DLP policies such as application execution blocking and file attachment blocking, alongside Windows. Extension features include OpenAPI integration, automatic backup of files taken outside the organization, and real-time webhooks. The company markets a human, real-time expert support team as a differentiator versus chatbot-based support, and highlights third-party validation including VB100 anti-malware certification, Microsoft Virus Initiative membership, TTA GS certification Grade 1, and cloud computing quality/performance verification.
The administration console is operated under the name Exosphere Labs and is localized in Korean, English and Japanese.
Business model
Subscription software-as-a-service: customers create an organization account, install endpoint agents, and manage policy centrally from a cloud admin console. Multiple plans are offered according to business needs, with a free trial, product demonstrations, and a partner program for resellers.
Paid service plans tiered to business needs, entered via a free trial; the site also points prospective customers to government support programs that can offset adoption cost.
Traction
Approximately 8,000 organizations are stated to use the service, a level said to have been reached within three years of launch. Testimonials reference multi-year use and daily security reporting.

Market position
Marketed as an SMB-focused all-in-one PC security service in Korea, claiming adoption by roughly 8,000 organizations within three years of launch and holding anti-malware and service-quality certifications; customer feedback notes it is not yet a certified anti-virus option for large enterprises or public institutions.
Positions itself as a single service covering both malware defense and DLP, with simplified functions and an administrator GUI intended for non-experts, macOS DLP coverage, real-time policy propagation, daily security reports, and a staffed real-time support team rather than chatbot-only support.
Technology
Cloud-based management console with endpoint agents for Windows and macOS. Policy changes are said to apply in real time. Security functions span malware and ransomware defense, device and media control, application execution control, web filtering, screen capture and print controls, and personal data detection and encryption. Integration surfaces include an OpenAPI, real-time webhooks, and automatic backup of exported files.
Go-to-market
Self-serve free trial and online sign-up combined with inbound sales channels (adoption inquiry, demonstration request), a partner application program, and promotion of government subsidy programs to reduce adoption cost. Localized interfaces in Korean, English and Japanese support sales beyond Korea.
Small and medium-sized businesses and small organizations needing PC security and data-leak prevention without dedicated security specialists; customer testimonials emphasize ease of administration for SMBs.
Geography
Headquartered in South Korea, with the admin console available in Korean, English and Japanese; a Japanese-branded interface (EXOセキュリティ) and a jiransoft.jp contact address appear in the console.
Risks & controversies
Customer feedback published on the company's own site notes the product is not certified as an anti-virus solution for large enterprises or public institutions, a gap for larger accounts.
